Title: Improvements in cathode structures for vacuum thermionic tubes
IPC: C04B35/51
Filed: 1924-01-01
Abstract: 209,415. Westinghouse Electric & Manufacturing Co., (Assignees of Freeman, H. M., and Wade, W. G.). Jan. 8, 1923, [Convention date]. Vacuum tubes.-An equipotential cathode is rendered thermionically active by conduction through material interposed between the cathode and a heating-element energized by alternating current. As shown in Figs. 1 and 3, a U-shaped filament 8 is threaded through perforations in a cylinder 5 of refractory insulating material such as zircon, on which the cathode, in the form of a tube 17 coated with an active material such as barium or strontium oxide, fits closely. The legs of the filament are arranged close together so that the magnetic fields neutralize each other. The cathode may be connected by a conductor 22 with one of the leads of the filament. A support 18 is connected with the cathode through a spring 21. One or two helical grids 24 and an anode 23 are mounted around the cathode and are supported on a re-entrant stem 2. In a modification, the legs of the filament are threaded through separate tubes of refractory material, and a cap on a tubular cathode is welded to a support, and connected with the bent portion of the filament; the support may act as a leading-in wire for the cathode. In another modification, the cathode consists of an oxide-coated platinum strip wound around refractory members, or around the legs of the filament, which may be covered with an insulating oxide, such as magnesium oxide. In the arrangement shown in Fig. 7, the heating-element consists of a U-shaped tungsten ribbon 48 the legs of which are separated by a strip 51 of mica, and the cathode consists of oxide-coated strips 52, 53 of nickel spaced from the ribbon by mica 54, 55, the whole being bound together by collars 56, 57 and attached to a support 58. The valve mav be used as an amplifier or rectifier with the cathode connected with one of the leads of the heating-element, or with a separate plug in the cap. A second grid mounted adjacent to the cathode may be maintained at a positive potential. The Specification as open to inspection under Sect. 91 (3) (a) comprises also cathodes heated by radiation or electron bombardment. In the arrangement shown in Fig. 10 (Cancelled), two sections 67, 68 of a filament are mounted inside the cathode 65 and are welded to a nickel support 69. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of thin-walled tubing from thermoplastic materials
Inventor: NOBLE DENNIS ALEXANDER JOHN
IPC: B29C48/09
Filed: 1957-01-01
Abstract: <PICT:0828851/IV (a)/1> <PICT:0828851/IV (a)/2> <PICT:0828851/IV (a)/3> In the extrusion of thermoplastic material through a die to form a seamless tube by a process in which the tube is expanded by means of entrapped gas and later collapsed, the tube is cooled below its setting temperature between the die and the point of collapse by continuously cooling the entrapped gas and continuously circulating the gas within the tube in such a path that it is directed on to the internal surface of the tube.  The gas may be air, and the thermoplastic material may be polyethylene, polystyrene, nylon, polyvinyl chloride, vinyl chloride copolymers, vinylidene chloride copolymers, cellulose acetate, cellulose acetate-butyrate, ethyl cellulose, methyl methacrylate polymers, or polyvinyl-formal, -acetal or -butyral.  The gas may be cooled while passing about the longitudinal axis of the tube-and may be so circulated that the thermo, plastic material sets within the first third of the path of travel of the tube from the die to the point of collapse. Preferably, the gas is so circulated that it passes about the longitudinal axis of the tube towards the die, is directed radially outwards towards the internal surface of the tube, is passed along the internal surface of the tube away from the die, and is then drawn inwardly, in a converging manner, towards the axis of the tube for recirculation.  As shown, suitable apparatus comprises a die 1 having an annular extrusion orifice 2 supplied with thermoplastic material via inlet 5 and ring passage 4, a gas inlet 18 fitted with valve 19, a pair of nip rollers (not shown) spaced from the die orifice to draw the tube therefrom and collapse it, a gas circulating device and a gas cooling device.  The circulating device may be a fan 11 driven by an electric motor 10, mounted between the die and the open-ended cylinder 9, so as to draw the gas through the cylinder and the perforated plate 8 and ring plate 7 towards the fan.  The fan assembly is supported by the table 6.  The fan may be of the centrifugal type having spaced around its periphery a number of stationary gas deflectors 13 so set that they tend to strip the gas from the fan and direct it radially outwards, or an impeller type fan 23 ((Fig. 3) may be used in conjunction with a peaked deflecting surface 24.  The cooling device may be placed at the open end of the cylinder remote from the fan so as to cool the gas drawn towards the fan, and may consist of a grid of pipes 14 fitted with fins 15 and having inlet and outlet supply pipes 16, 17 carrying a cooling fluid. Specifications 654,550 and 716,160 are referred to.

IPC: A61K6/00
Filed: 2005-07-04
Abstract: Methods are provided for the synthesis of polymer conjugates of cytokines, chemokines, growth factors, polypeptide hormones and receptor-binding antagonists thereof, which conjugates retain unusually high receptor-binding activity. Preparation of polymer conjugates according to the methods of the present invention diminishes or avoids steric inhibition of receptor-ligand interactions that commonly results from the attachment of polymers to receptor-binding regions of cytokines, chemokines, growth factors and polypeptide hormones, as well as to agonistic and antagonistic analogs thereof. The invention also provides conjugates and compositions produced by such methods. The conjugates of the present invention retain a higher level of receptor-binding activity than those produced by traditional polymer coupling methods that are not targeted to avoid receptor-binding domains of cytokines, chemokines, growth factors and polypeptide hormones. The conjugates of the present invention also exhibit an extended half-life in vivo and in vitro compared to unconjugated cytokines, chemokines, growth factors and polypeptide hormones. The present invention also provides kits comprising such conjugates and/or compositions, and methods of use of such conjugates and compositions in a variety of diagnostic, prophylactic, therapeutic and bioprocessing applications.

IPC: H04M3/48
Filed: 1994-01-28
Abstract: A method of effecting automatic callback in a mobile telecommunication system. A calling subscriber is permanently connected to a public switched telephone network and a called subscriber is a mobile unit which moves in the public land mobile network. A centrally located home location register keeps an account of where all mobiles registered in the mobile telecommunication network are located, with the aid of local databases, so-called visitor location registers. The called subscriber calls the called subscriber and finds that the subscriber is busy. The calling subscriber then dials a code, wherewith a reference is stored in a queue in the home location register, this queue relating to the called subscriber. When the called subscriber is free to receive a call, the calling subscriber is informed to this effect. The calling subscriber then lifts his telephone receiver and a connection is set-up between the two subscribers. When the called subscriber answers, the call is considered to have been connected. The home location register (HLR) then removes the reference from the queue.

Granted: 1967-12-08
Abstract: 1,122,068. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 1 Dec., 1966, No. 52104/65. Heading H2K. [Also in Divisions G1 and H4] Light pulses modulated in accordance with the current variations on a high voltage line are transmitted via a light guide to a location at low (earth potential) where the pulses are detected for measurement or control purposes. The devices at high potential include a current 'ransformer coupled to the line, a generator of square pulses of constant width and repetition rate, and a light-emitting device, e.g. a gallium arsenide diode. Pulses from the generator are width modulated in accordance with variations in the line current and amplified before supplying the light source. At earth potential the light transmitted by the fibre optic guide is detected by a photo-diode and the amplified and demodulated signal used for measurement of the actual value, the r.m.s., or the instantaneous value of the line current or to the control of protective apparatus, e.g. a circuit-breaker. The circuit (Fig. 3, not shown), for modulating the square pulses from the generator is transistorized and supplied from the line. Square pulses of a frequency much higher than the A.C. line variations (in the case of an A.C. line) are applied at e i , charge up a capacitor (C 1 ) and cause transistors (T 1 , T 2 ) to conduct, producing an output voltage e 0 . The duration of conduction of the first transistor (T 1 ) after the end of a pulse e;, depends on the voltage at a point (V e ) which follows variations in the line current. The receiver circuit (Fig. 4, not shown), includes an amplifying transistor (T 3 ) and integrating and D.C. filter arrangements. Various constructions for the insulating structure, adapted to include a light guide, are described (Figs. 5-7, not shown).

Title: Improvements in domestic water heaters and low pressure steam generators
IPC: F24H1/36
Filed: 1935-01-02
Abstract: 443,802. Water-heaters and steamgenerators. WARD, G. F., 3, Bertram Drive North, Hoylake, Cheshire. Jan. 2, 1935, No. 112. [Class 64 (i)] [See also Groups XI and XII] A gas-fired water-heater or low-pressure steam-generator comprises an open-ended combustion tube 1 the bore of which adjacent the burner 12 is restricted by a sleeve 16 having passages 18b in which an auxiliary air supply is heated, the air being drawn through the passages into the tube 1 by the injector action of the gases passing through the sleeve, the bore of which may be of Venturi form as shown. In the construction shown, the air passages 18b are formed by longitudinal or helical grooves on the outer face of the sleeve. A twisted strip baffle 18 may be arranged in the flue. The domestic waterheater shown comprises an annular waterchamber 5 mounted in diaphragms 9, 10 around the flue, and a thermostat 14 arranged in a pocket 13 at the side of the chamber to control the gas supply. A low-pressure steam-generator is described comprising vertical flue tubes extending between upper and lower tube plates, each tube being provided with a sleeve as above described and having a separate gas jet below it.

Title: Improvements to dampers and to damped pneumatic suspensions
IPC: F16F9/084
Filed: 1959-01-21
Abstract: 888,071. Hydraulic shock absorbers; adjusting body height. MILLY, L. C. E. Jan. 2, 1959, No. 176/59. Classes 108(2) and 108(3). In a combined shock absorbing and suspension device for road vehicles, a double acting piston and cylinder type, shock absorber has a spring-loaded compensating piston 5, which has a one-way valve 6. In operation, when the piston moves, the valves carried in the piston open before the compensating piston 5 is lifted from its seat 4. A helical spring 16 is mounted between end plates 2, 9. The spring 16 is associated with a flexible rubber-like enclosure 17, which may contain gas under pressure as described in Specification 821,230. The device is selflevelling, air being pumped into the enclosure 17 by a pump comprising a tubular socket 18, integral with the lower end plate 9, which slides on the damper body 1. Air is drawn into the pump through an orifice 29 and a valve 19, and pushed into the enclosure 17 through a valve 27. In operation, if the ground clearance is below the desired amount, springs 22, 23, which abut an end 24 of a distributer 20 bring about a downward displacement of the distributer 20. Consequently, an orifice 26 sealed by the valve 27 will move into a position opposite a callibrated orifice 28 of the pump body 18. From this moment, air drawn into the pump by suction will be compressed into the enclosure 17 through the valve 27. Conversely, if the mean equilibrium height is displaced upwards, a heel 30 of the distributer 20 will raise a valve 31 and bring about a fall in pressure due to the escape of air through an aperture 32. The movements of the distributer 20 may be damped by a hydraulic dashpot instead of frictionally as shown. Compressed air may be supplied to the enclosure 17 from a separate source outside the device through suitable levelling valves. All the suspension devices in a road vehicle may be supplied from the same source of compressed air.

[Class 135] In an inlet supply valve for automatic flushing tanks in which the valve member 10 is normally adjusted with respect to an orifice member 5 to allow a restricted flow of liquid to the tank and is operable through lever means 14 on a change in liquid level in the tank to increase the passage for liquid so as to flush out any sediment or deposit, the valve member or the orifice member or both are constructed of fired ceramic material, glass, or other hard material. A steatite ceramic material having a hardness of about 9 on Mohs scale is specially suitable. As shown in Fig. 2, the valve casing 3 is coupled to a supply elbow 2 by a union 4 and has a bracket 6 to secure it to the tank 9 which contains an automatic discharge valve. The orifice member 5 and a strainer 20 are clamped by the union 4. The valve member is screwed to a stem 18 of square or other section slidable with line contact in the outlet bore 19. The valve operating lever 14 is pivoted at 13 and secured to a float arm 16 by a set screw 15. The valve closing movement of the lever 14 is limited by an externally adjustable screw 21 engaging the toe 14c of the lever. The depending flush tube 11 has slots 11a to accommodate the lever 14. In a modification, the lower end of the stem 18 is bifurcated and straddles the lever 14. In another form, the stem 18 is of circular section and has a close fit in the bore 19, the outlet and the flush tube being in this case offset from the axis of the valve member.

[Also in Group V] In the firing of lamelliform ceramic ware such as floor tiles, the green ceramic material is placed on a refractory support which has been coated with a clay and limestone composition which prevents the ceramic material from moving on the support during firing and therefore confines all shrinkage to the thickness of the ware, but allows easy removal of the ware after it has been fired. The ceramic material consists of 5 to 20 per cent kaolin and talc, 0.1 to 1-5 per cent colloidal substances such as bentonite and sodium phosphate, and the remainder is lean materials such as glass scrap, porcelain scrap and sand. The clay and limestone composition includes colloidal substances such as peptized bentonite and sodium pyrophosphate. While on the support and before firing the ceramic material may be divided by suitably directed water jets (see Group V).
